NAME

Geo::JapanMesh - Convert between latitude/longitude and Japanese geographical mesh code

SYNOPSIS

# To convert Japanese geographical mesh code
use Geo::JapanMesh;

# From latitude/longitude to mesh code

my $code = latlng2japanmesh( $lat, $lng, $level );

# From mesh code to latitude/longitude rectangle

my ( $minlat, $minlng, $maxlat, $maxlng, $centlat, $centlng, $level ) = japanmesh2rect( $code );

# From mesh code to center latitude/longitude 

my ( $centlat, $centlng, $level ) = japanmesh2latlng( $code );

# To convert DoCoMo iArea mesh code
use Geo::JapanMesh qw(:iareamesh);

# From latitude/longitude to mesh code

my $code = latlng2iareamesh( $lat, $lng, $level );

# From mesh code to latitude/longitude rectangle

my ( $minlat, $minlng, $maxlat, $maxlng, $centlat, $centlng, $level ) = iareamesh2rect( $code );

# From mesh code to center latitude/longitude 

my ( $centlat, $centlng, $level ) = iareamesh2latlng( $code );

# To use both Japanese geographical and DoCoMo iArea mesh code
use Geo::JapanMesh qw(:DEFAULT :iareamesh);
